install_fw_rpi.sh -- syntax error line 29

[ghost]

The script command on line 29 throws a syntax error. The IF check is "=" rather than "==" for the string compare.

Current command:

Download latest firmware

if [ $1 = "beta" ]; then

Should be:

if [ $1 == "beta" ]; then

Found this while attempting to update an older ZUMSPOT MMDVM board's firmware. Manually updated the script and was able to get a successful firmware update with that minor change.
